Overlapse makes it simple to create jaw-dropping, frame by frame timelapses.
An overlay helps to line up with your last shot
Notifications for taking the next picture (and nothing else)

Make your own creative Overlapse or use one of these ideas:
Selfie a Day
Growing Plants
Trees Changing Colors
Seasons Changing
Pregnant Selfies
Baby Growing

You can create multiple projects and import pictures that you have in your camera roll.

The app is free to use, but you can perform the in-app purchase to remove ads and watermarks.

Go forth and create art!
